The method now used for the transparent silicate of fire-proof glass is to select the glass process, cutting treatment and chemical polishing of the original sheet, and then the super physical and film coating of infrared reflection of fire tempering. Compared with the existing skills, the glass now produced has high mechanical strength, so the fire-proof glass has excellent thermal stability, reduces the expansion coefficient of the glass and cleans up the micro cracks on the glass surface, Then complete the advantages of fireproof glass, etc.

At present, the standard of fire-proof glass is the fire-proof glass obtained by physical and chemical treatment and float glass. Its fire resistance is characterized by the following facts. When one side of the glass is exposed in the flame, the glass can avoid the penetration of fire and hot air or the emergence of fire flame on the back of the glass, which is conducive to the initial detection of fire and ensure the guarantee of escape, so that the affected people can evacuate the site at a satisfactory time, And strive for time for rescue operation in case of disaster.

Now, with the development of science and technology and the continuous promotion of people's life, due to the increasing urban population, the increasing density and the construction volume of urban development, high-rise buildings have to become the construction group of buildings, and the fire protection design requirements of high-rise buildings are more stringent. As the designer of the construction industry, it is necessary to formulate the fire protection design of high-rise buildings, which is respect for the industry and the life of construction users, Building curtain wall in high-rise building is an important operation of fire protection design in high-rise building design. It is very important to collect information, analyze and discuss.

With the gradual acceleration of domestic economic construction, there are many large-scale public buildings, such as underground space. Considering the structure and beauty of buildings, more and more fire isolation are made of fire-proof glass partitions. After analyzing the problems existing in the design and the construction of fire-proof glass partitions in current construction projects, appropriate solutions are put forward to ensure that the fire-fighting policy does not decline, and the construction puts forward a reasonable proposition.
